EXPLOSIVE TOY.

Specification of Letters Patent.

Patented Sept. 19, 1911.

Application filed November 18, 1910. Serial No. 593,004.

T 0 all whom it may concern:

Be it known that I, Amnnrr A. Cour, a citizen of the United States. residing at the city of St. Louis, Missouri, have invented a certain new and useful Explosive Toy, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to an explosive toy andmore particularly to one in which the by the rupture of a diaphragm of paper or similar material by air pressure. In my device the air pressure is caused by the collapse of a flexible impervious body such as rubber.

The object of my invention is to produce a device of the class above indicated which will be simple in construction so that it may not only be manufactured at small cost but will not be liable toget out of order.

A further object of my invention is to so construct the device that it will be strong and eflicient.

In the accompanying drawings which illustrate one form of device made in accordance with my invention, Figure 1 is a longitudinal section showing the clamping member held in position against the collapsible member; Fig. 2 is an end view of one of the handles; Fig. 3 is a view similar to Fig. 1 but showing the clamping member separated from the collapsible member; Fig 4 is a plan view of the handle holding the clamping member and Fig. 5 is a plan view of the handle holding the collapsible member.

Like marks of reference refer to similar parts in the several views in the drawings.

6 and 7 are two handles preferably formed of strips of metal. The handle 6 has formed'at one end a circular loop 17, as best shown in Fig. 5. This circular loop 17 is adapted to receive a cup-shaped member 8 in which is secured a half ball 9 of rubber. This half ball 9 may be cemented in the cup-shaped member 8 in order to prevent its displacement. The manner of operating the device, however, is such as to drive the half ball 9 in the cup 8 and consequently the ball need not be cemented. The cup-shaped member 8 is secure in the opening loop 17 by means of pieces 10 which are partially punched out of the loop 17 as best shown in Figs. 1 and The face of the cup-shaped member 8 is provided with an opening 11 over which a diaphragm 12 is adapted to be clamped. This opening 11 is surrounded by a projecting lip 13. The projecting lip 13 is adapted to enter an 1 1 in the clamping member 15, as best shown in Fig. 1 and thus tightly stretch the diaphragm 12. This stretching of the diaphragm 12 insures a louder and sharper report than would be otherwise secured. The clamping member 15 is pivoted to the handle 7 by means of trunnions 16 formed on the ends of the handle and entering openings 18 in the clamping member 15. The two handles are pivoted together by means of a pin 19. The ends of the handle (5 are secured together-by means of a dovetailed projection 20 formed on one end of the handle and entering a corresponding opening in the other, as best shown in Fig. 2.

As is shown in Figs. .1 and 2 the half ball 9 is not of uniform thickness throughout but is considerably thicker at the edges than at the central portion. This strengthens the hall where it is most likely to be injured during use and thus causes a saving in the amount of rubber used. Furthermore, the weakening of the central part of the ball allows the ball to be collapsed more readily and thus makes the device easier to use than one in which the ball is of uniform thickness throughout.

The operation of my device will be evident. The diaphragm 12 of paper is placed between the members 8 and 15 while they are in the position shown in Fig. 3 and the handles are then drawn together so as to bring the clamping member down against the member 8, as shown in Fig. 1. This firmly clamps the diaphragm between the two members and the entrance of the projecting lip 13 in the opening 1 1 tightly stretches the portion of the diaphragm which is over the opening 11. By striking thethin central portion of the half ball 9 against any suitable object it is collapsed as shown in dotted lines in Fig. 1 and the air pressure thus generated ruptures the diaphragm 12 causing a' loud and sharp report.

I find that the use of the projecting lip 13 not only insures a sharper and louder report when the diaphragm is ruptured but also enables the diaphragm to be ruptured by a lighter blow of the ball 9 than if the said lip were not used. This reduction of the amount of force necessary to be applied to the ball 9 is a very important feature in practice and makes my device commercially superior to those heretofore used.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

l. The combination with a pair of relatively movable supporting members, of a clamping member carried by one of said supporting members and provided with an opening, a second clamping member pivoted to the other supporting member and also provided with an opening, and a hollow body of impervious flexible material carried by one of said clamping members for forcing air through said openings.

2. The combination with a pair of relatively movable supportingmembers, of a clamping member carried by one of said supporting members and provided with an opening, a hollow body of impervious flexible material carried by said clamping member for forcing air through said opening, and second clamping member pivoted to the other of said supporting members and also provided With an opening.

3. The combination with a pair of relatively' movable clamping members, one of said members being provided With an opening and the other also having an opening surrounded by a lip of smaller diameter than said first named opening, whereby a sheet of material is stretched over said lip, of a collapsible body of impervious material carried by one of said members for forcing air through said openings.

4. The combination with a pair of relatively movable clamping members, one of said members being provided with an opening and the other also havin an o ening surrounded by a beveled lip of smal er diameter than said first mentioned opening Whereby the sheet of material is stretched over said lip, of a collapsible body of impervious material carried by one of said members for forcing air through said openings.

In testimony whereof, I have hereunto set my hand and affixed my seal in the presence of the two subscribing witnesses.
